In some aspects, the disclosure relates to isolated AAV capsid proteins and isolated nucleic acids encoding the same.

RELATED APPLICATIONS

The application is a National Stage Application of PCT/US2015/016691, filed Feb. 19, 2015, and entitled “RECOMBINANT AAVS HAVING USEFUL TRANSCYTOSIS PROPERTIES”, which claims the benefit under 35 U.S.C. § 119(e) to U.S. Provisional Application Ser. No. 61/942,002, entitled “RECOMBINANT AAVS HAVING USEFUL TRANSCYTOSIS PROPERTIES”, filed on Feb. 19, 2014, the entire content of each of which is incorporated by reference herein.

FIELD

The disclosure in some aspects relates to isolated nucleic acids, compositions, and kits useful for identifying adeno-associated viruses in cells. In some aspects, the disclosure provides novel AAVs and methods of use thereof as well as related kits.

BACKGROUND

Adeno-associated virus (AAV) is a small (˜26 nm) replication-defective, nonenveloped virus, that depends on the presence of a second virus, such as adenovirus or herpes virus, for its growth in cells. AAV was discovered in 1960s as a contaminant in adenovirus (a cold causing virus) preparations. Its growth in cells is dependent on the presence of adenovirus and, therefore, it was named as adeno-associated virus. AAV can infect both dividing and non-dividing cells and may incorporate its genome into that of the host cell. These features make AAV a very attractive candidate for creating viral vectors for gene therapy.

SUMMARY

The disclosure in some aspects relates to novel AAVs for gene therapy applications. Aspects of the disclosure relate to variants of AAV9 that have unique transcytosis properties. In some embodiments, recombinant AAVs (rAAVs) disclosed herein have a transduction efficiency similar to rAAV9 but improved safety profiles, particularly for muscle and lung gene delivery. Accordingly, in some embodiments, rAAV vectors are particularly useful for gene therapy of muscular, lung or other disorders. In some embodiments, a structural analysis of the ClvD8 capsid protein (a variant of the AAV9 capsid) was performed using the recently established AAV9 capsid structure as a template. In some embodiments, this analysis revealed differences in amino acids at position 647 and in other residues located at a position corresponding to AAV9 capsid protrusions that surrounds the icosahedral 3-fold axis of AAV9 VP3 protein. In some embodiments, amino acids in these protrusions play a role in receptor binding and cellular transduction.

In some embodiments, amino acids involved in peripheral (primarily liver) tissue transduction by IV delivery of rAAV9 were identified. In some embodiments, single and combinatory mutations for each of the amino acids on the AAV9 capsid that are mutated in AAV-ClvD8 were produced and evaluated for biodistribution profiles following delivery by intranasal or intramuscular injection. In some embodiments, a novel capsid mutant of AAV9, referred to as AAV9HR, produced local tissue-restricted expression and genome persistence by intramuscular and intranasal delivery, and produced low levels of expression in liver when delivered by intravascular (IV), intramuscular (IM) and intranasal (IN) delivery routes. In some embodiments, AAV9.HR displayed a blood clearance pattern similar to that of rAAV9 wt after IV, IM, and IN administration indicating that its ability to cross vascular barrier from tissue to vessel was not impaired.

Accordingly, aspects of the disclosure relate to recombinant AAVs (rAAVs) comprising an AAV capsid protein having an amino acid sequence selected from the group consisting of: SEQ ID NOs: 2-7, and compositions comprising the same. In some embodiments, compositions provided herein that comprise an rAAV further comprise a pharmaceutically acceptable carrier. In some embodiments, host cells are provided that contain a nucleic acid that comprises a coding sequence selected from the group consisting of: SEQ ID NO: 9-14 that is operably linked to a promoter, such that the cells are engineered to expess rAAV capsids.

Accordingly, in some embodiments, the rAAV can be used to infect cells of target tissue (e.g., muscle tissue) so as to engineer cells of the tissue to express an antigen-binding protein, such as an antibody or fragment thereof. In some embodiments, the protein is a central nervous system (CNS) protein. In some embodiments, the CNS protein is aspartoacylase (ASPA). In some embodiments, the ASPA is human ASPA. Accordingly, in some embodiments, the rAAV can be used to infect cells of a target tissue (e.g., CNS tissue) so as to engineer cells of the tissue to express ASPA.

In some embodiments, the protein is a secreted tumor suppressor protein. In some embodiments, the secreted tumor suppressor protein is selected from the group consisting of IGFBP7 and SRPX.

In other embodiments, the at least one transgene of an rAAV encodes a small interfering nucleic acid, such as a miRNA.

In some embodiments, the transgene comprises one or more elements that mediate tissue-specific expression. In some embodiments, the transgene of an rAAV expresses a transcript that comprises at least one binding site for a miRNA, wherein the miRNA inhibits activity of the transgene, in a tissue other than the target tissue, by hybridizing to the binding site. In some embodiments, the transgene of an rAAV comprises a tissue specific promoter or inducible promoter. In some embodiments, the tissue specific promoter is a liver-specific thyroxin binding globulin (TBG) promoter, a insulin promoter, a glucagon promoter, a somatostatin promoter, a pancreatic polypeptide (PPY) promoter, a synapsin-1 (Syn) promoter, a creatine kinase (MCK) promoter, a mammalian desmin (DES) promoter, a α-myosin heavy chain (a-MHC) promoter, or a cardiac Troponin T (cTnT) promoter.

Each of the limitations of the disclosure can encompass various embodiments of the disclosure. It is, therefore, anticipated that each of the limitations of the disclosure involving any one element or combinations of elements can be included in each aspect of the disclosure. This disclosure is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings. The disclosure is capable of other embodiments and of being practiced or of being carried out in various ways.

DETAILED DESCRIPTION

In some embodiments, recombinant AAVs are provided herein that overcome shortcomings of existing rAAV technologies in that they have distinct transcytosis properties that make them useful for certain gene therapy and research applications.

In some aspects of the disclosure new AAV capsid proteins are provided that have distinct tissue targeting capabilities. In some embodiments, an AAV capsid protein is isolated from the tissue to which an AAV comprising the capsid protein targets. In some aspects, methods for delivering a transgene to a target tissue in a subject are provided. The transgene delivery methods may be used for gene therapy (e.g., to treat disease) or research (e.g., to create a somatic transgenic animal model) applications.

Isolated AAV Capsid Proteins and Nucleic Acids Encoding the Same

AAVs are natural inhabitants in mammals. AAVs isolated from mammals, particularly non-human primates, are useful for creating gene transfer vectors for clinical development and human gene therapy applications. The disclosure provides in some aspects novel AAV capsid proteins that have been development through functional mutagenesis. Protein and amino acid sequences as well as other information regarding the AAVs capsid are set forth in the sequence listing.

In some embodiments, an AAV capsid is provided that has an amino acid sequence of SEQ ID NO: 1 with one or more of the following amino acid alterations: Y445H, H527Y, I647T, and R533S.

In some embodiments, an AAV capsid is provided that has an amino acid sequence of SEQ ID NO: 1 with one or more of the following amino acid alterations: Y445H, H527Y, I647T, and R533S and up to 5, up to 10, up to 20, up to 30, up to 40, up to 50, up to 100 other amino acid alternations (e.g., conservative amino acid sustitutions).

An example of an isolated nucleic acid that encodes an AAV capsid protein is a nucleic acid having a sequence selected from the group consisting of: SEQ ID NO: 9-14 as well as nucleic acids having substantial homology thereto. In some embodiments, isolated nucleic acids that encode AAV capsids are provided that have sequences selected from: SEQ ID NO: 9, 10, 11, 12, 13, and 14.

In some embodiments, nucleic acids are provided that encode an AAV capsid having one or more of the following amino acid alterations: Y445H, H527Y, I647T, and R533S based on the amino acid sequence of SEQ ID NO: 1.

In some embodiments, nucleic acids are provided that encode an AAV capsid having one or more of the following amino acid alterations: Y445H, H527Y, I647T, and R533S based on the amino acid sequence of SEQ ID NO: 1 and up to 5, up to 10, up to 20, up to 30, up to 40, up to 50, up to 100 other amino acid alternations.

In some embodiments, a fragment (portion) of an isolated nucleic acid encoding a AAV capsid sequence may be useful for constructing a nucleic acid encoding a desired capsid sequence. Fragments may be of any appropriate length (e.g., at least 9, at least 18, at least 36, at least 72, at least 144, at least 288, at least 576, at least 1152 or more nucleotides in length). The fragment may be a fragment that does not encode a peptide that is identical to a sequence of SEQ ID NO: 1. For example, a fragment of nucleic acid sequence encoding a variant amino acid (compared with a known AAV serotype) may be used to construct, or may be incorporated within, a nucleic acid sequence encoding an AAV capsid sequence to alter the properties of the AAV capsid. For example, a nucleic sequence encoding an AAV variant may comprise n amino acid variants (e.g., in which n=1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more) compared with a known AAV serotype (e.g., AAV9). A recombinant cap sequence may be constructed having one or more of the n amino acid variants by incorporating fragments of a nucleic acid sequence comprising a region encoding a variant amino acid into the sequence of a nucleic acid encoding the known AAV serotype. The fragments may be incorporated by any appropriate method, including using site directed mutagenesis. Thus, new AAV variants may be created having new properties.

In some cases, fragments of capsid proteins disclosed herein are provided. Such fragments may at least 10, at least 20, at least 50, at least 100, at least 200, at least 300, at least 400, at least 500 or more amino acids in length. In some embodiments, chimeric capsid proteins are provided that comprise one or more fragments of one or more capsid proteins disclosed herein.

“Homology” refers to the percent identity between two polynucleotides or two polypeptide moieties. The term “substantial homology”, when referring to a nucleic acid, or fragment thereof, indicates that, when optimally aligned with appropriate nucleotide insertions or deletions with another nucleic acid (or its complementary strand), there is nucleotide sequence identity in about 90 to 100% of the aligned sequences. When referring to a polypeptide, or fragment thereof, the term “substantial homology” indicates that, when optimally aligned with appropriate gaps, insertions or deletions with another polypeptide, there is nucleotide sequence identity in about 90 to 100% of the aligned sequences. The term “highly conserved” means at least 80% identity, preferably at least 90% identity, and more preferably, over 97% identity. In some cases, highly conserved may refer to 100% identity. Identity is readily determined by one of skill in the art by, for example, the use of algorithms and computer programs known by those of skill in the art.

As described herein, alignments between sequences of nucleic acids or polypeptides are performed using any of a variety of publicly or commercially available Multiple Sequence Alignment Programs, such as “Clustal W”, accessible through Web Servers on the internet. Alternatively, Vector NTI utilities may also be used. There are also a number of algorithms known in the art which can be used to measure nucleotide sequence identity, including those contained in the programs described above. As another example, polynucleotide sequences can be compared using BLASTN, which provides alignments and percent sequence identity of the regions of the best overlap between the query and search sequences. Similar programs are available for the comparison of amino acid sequences, e.g., the “Clustal X” program, BLASTP. Typically, any of these programs are used at default settings, although one of skill in the art can alter these settings as needed. Alternatively, one of skill in the art can utilize another algorithm or computer program which provides at least the level of identity or alignment as that provided by the referenced algorithms and programs. Alignments may be used to identify corresponding amino acids between two proteins or peptides. A “corresponding amino acid” is an amino acid of a protein or peptide sequence that has been aligned with an amino acid of another protein or peptide sequence. Corresponding amino acids may be identical or non-identical. A corresponding amino acid that is a non-identical amino acid may be referred to as a variant amino acid.

Alternatively for nucleic acids, homology can be determined by hybridization of polynucleotides under conditions which form stable duplexes between homologous regions, followed by digestion with single-stranded-specific nuclease(s), and size determination of the digested fragments. DNA sequences that are substantially homologous can be identified in a Southern hybridization experiment under, for example, stringent conditions, as defined for that particular system. Defining appropriate hybridization conditions is within the skill of the art.

A “nucleic acid” sequence refers to a DNA or RNA sequence. In some embodiments, proteins and nucleic acids of the disclosure are isolated. As used herein, the term “isolated” means artificially produced. As used herein with respect to nucleic acids, the term “isolated” means: (i) amplified in vitro by, for example, polymerase chain reaction (PCR); (ii) recombinantly produced by cloning; (iii) purified, as by cleavage and gel separation; or (iv) synthesized by, for example, chemical synthesis. An isolated nucleic acid is one which is readily manipulable by recombinant DNA techniques well known in the art. Thus, a nucleotide sequence contained in a vector in which 5′ and 3′ restriction sites are known or for which polymerase chain reaction (PCR) primer sequences have been disclosed is considered isolated but a nucleic acid sequence existing in its native state in its natural host is not. An isolated nucleic acid may be substantially purified, but need not be. For example, a nucleic acid that is isolated within a cloning or expression vector is not pure in that it may comprise only a tiny percentage of the material in the cell in which it resides. Such a nucleic acid is isolated, however, as the term is used herein because it is readily manipulable by standard techniques known to those of ordinary skill in the art. As used herein with respect to proteins or peptides, the term “isolated” refers to a protein or peptide that has been isolated from its natural environment or artificially produced (e.g., by chemical synthesis, by recombinant DNA technology, etc.).

The skilled artisan will also realize that conservative amino acid substitutions may be made to provide functionally equivalent variants, or homologs of the capsid proteins. In some aspects the disclosure embraces sequence alterations that result in conservative amino acid substitutions. As used herein, a conservative amino acid substitution refers to an amino acid substitution that does not alter the relative charge or size characteristics of the protein in which the amino acid substitution is made. Variants can be prepared according to methods for altering polypeptide sequence known to one of ordinary skill in the art such as are found in references that compile such methods, e.g. Molecular Cloning: A Laboratory Manual, J. Sambrook, et al., eds., Second Edition, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., 1989, or Current Protocols in Molecular Biology, F. M. Ausubel, et al., eds., John Wiley & Sons, Inc., New York. Conservative substitutions of amino acids include substitutions made among amino acids within the following groups: (a) M, I, L, V; (b) F, Y, W; (c) K, R, H; (d) A, G; (e) S, T; (f) Q, N; and (g) E, D. Therefore, one can make conservative amino acid substitutions to the amino acid sequence of the proteins and polypeptides disclosed herein.

Recombinant AAVs

In some aspects, the disclosure provides isolated AAVs. As used herein with respect to AAVs, the term “isolated” refers to an AAV that has been isolated from its natural environment (e.g., from a host cell, tissue, or subject) or artificially produced. Isolated AAVs may be produced using recombinant methods. Such AAVs are referred to herein as “recombinant AAVs”. Recombinant AAVs (rAAVs) preferably have tissue-specific targeting capabilities, such that a transgene of the rAAV will be delivered specifically to one or more predetermined tissue(s). The AAV capsid is an important element in determining these tissue-specific targeting capabilities. Thus, an rAAV having a capsid appropriate for the tissue being targeted can be selected. In some embodiments, the rAAV comprises a capsid protein having an amino acid sequence as set forth in any one of SEQ ID NOs 2-7, or a protein having substantial homology thereto.

Methods for obtaining recombinant AAVs having a desired capsid protein are well known in the art. (See, for example, US 2003/0138772), the contents of which are incorporated herein by reference in their entirety). Typically the methods involve culturing a host cell which contains a nucleic acid sequence encoding an AAV capsid protein (e.g., a nucleic acid having a sequence as set forth in any one of SEQ ID NOs 9-14) or fragment thereof; a functional rep gene; a recombinant AAV vector composed of, AAV inverted terminal repeats (ITRs) and a transgene; and sufficient helper functions to permit packaging of the recombinant AAV vector into the AAV capsid proteins.

The components to be cultured in the host cell to package a rAAV vector in an AAV capsid may be provided to the host cell in trans. Alternatively, any one or more of the required components (e.g., recombinant AAV vector, rep sequences, cap sequences, and/or helper functions) may be provided by a stable host cell which has been engineered to contain one or more of the required components using methods known to those of skill in the art. Most suitably, such a stable host cell will contain the required component(s) under the control of an inducible promoter. However, the required component(s) may be under the control of a constitutive promoter. Examples of suitable inducible and constitutive promoters are provided herein, in the discussion of regulatory elements suitable for use with the transgene. In still another alternative, a selected stable host cell may contain selected component(s) under the control of a constitutive promoter and other selected component(s) under the control of one or more inducible promoters. For example, a stable host cell may be generated which is derived from 293 cells (which contain E1 helper functions under the control of a constitutive promoter), but which contain the rep and/or cap proteins under the control of inducible promoters. Still other stable host cells may be generated by one of skill in the art.

The recombinant AAV vector, rep sequences, cap sequences, and helper functions required for producing the rAAV of the disclosure may be delivered to the packaging host cell using any appropriate genetic element (vector). The selected genetic element may be delivered by any suitable method, including those described herein. The methods used to construct any embodiment of this disclosure are known to those with skill in nucleic acid manipulation and include genetic engineering, recombinant engineering, and synthetic techniques. See, e.g., Sambrook et al, Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Press, Cold Spring Harbor, N.Y. Similarly, methods of generating rAAV virions are well known and the selection of a suitable method is not a limitation on the present disclosure. See, e.g., K. Fisher et al, J. Virol., 70:520-532 (1993) and U.S. Pat. No. 5,478,745.

In some embodiments, recombinant AAVs may be produced using the triple transfection method (described in detail in U.S. Pat. No. 6,001,650). Typically, the recombinant AAVs are produced by transfecting a host cell with an recombinant AAV vector (comprising a transgene) to be packaged into AAV particles, an AAV helper function vector, and an accessory function vector. An AAV helper function vector encodes the “AAV helper function” sequences (i.e., rep and cap), which function in trans for productive AAV replication and encapsidation. Preferably, the AAV helper function vector supports efficient AAV vector production without generating any detectable wild-type AAV virions (i.e., AAV virions containing functional rep and cap genes). Non-limiting examples of vectors suitable for use with the present disclosure include pHLP19, described in U.S. Pat. No. 6,001,650 and pRep6cap6 vector, described in U.S. Pat. No. 6,156,303, the entirety of both incorporated by reference herein. The accessory function vector encodes nucleotide sequences for non-AAV derived viral and/or cellular functions upon which AAV is dependent for replication (i.e., “accessory functions”). The accessory functions include those functions required for AAV replication, including, without limitation, those moieties involved in activation of AAV gene transcription, stage specific AAV mRNA splicing, AAV DNA replication, synthesis of cap expression products, and AAV capsid assembly. Viral-based accessory functions can be derived from any of the known helper viruses such as adenovirus, herpesvirus (other than herpes simplex virus type-1), and vaccinia virus.

In some aspects, the disclosure provides transfected host cells. The term “transfection” is used to refer to the uptake of foreign DNA by a cell, and a cell has been “transfected” when exogenous DNA has been introduced inside the cell membrane. A number of transfection techniques are generally known in the art. See, e.g., Graham et al. (1973) Virology, 52:456, Sambrook et al. (1989) Molecular Cloning, a laboratory manual, Cold Spring Harbor Laboratories, New York, Davis et al. (1986) Basic Methods in Molecular Biology, Elsevier, and Chu et al. (1981) Gene 13:197. Such techniques can be used to introduce one or more exogenous nucleic acids, such as a nucleotide integration vector and other nucleic acid molecules, into suitable host cells.

A “host cell” refers to any cell that harbors, or is capable of harboring, a substance of interest. Often a host cell is a mammalian cell. A host cell may be used as a recipient of an AAV helper construct, an AAV minigene plasmid, an accessory function vector, or other transfer DNA associated with the production of recombinant AAVs. The term includes the progeny of the original cell which has been transfected. Thus, a “host cell” as used herein may refer to a cell which has been transfected with an exogenous DNA sequence. It is understood that the progeny of a single parental cell may not necessarily be completely identical in morphology or in genomic or total DNA complement as the original parent, due to natural, accidental, or deliberate mutation.

As used herein, the term “cell line” refers to a population of cells capable of continuous or prolonged growth and division in vitro. Often, cell lines are clonal populations derived from a single progenitor cell. It is further known in the art that spontaneous or induced changes can occur in karyotype during storage or transfer of such clonal populations. Therefore, cells derived from the cell line referred to may not be precisely identical to the ancestral cells or cultures, and the cell line referred to includes such variants.

As used herein, the terms “recombinant cell” refers to a cell into which an exogenous DNA segment, such as DNA segment that leads to the transcription of a biologically-active polypeptide or production of a biologically active nucleic acid such as an RNA, has been introduced.

As used herein, the term “vector” includes any genetic element, such as a plasmid, phage, transposon, cosmid, chromosome, artificial chromosome, virus, virion, etc., which is capable of replication when associated with the proper control elements and which can transfer gene sequences between cells. Thus, the term includes cloning and expression vehicles, as well as viral vectors. In some embodiments, useful vectors are contemplated to be those vectors in which the nucleic acid segment to be transcribed is positioned under the transcriptional control of a promoter. A “promoter” refers to a DNA sequence recognized by the synthetic machinery of the cell, or introduced synthetic machinery, required to initiate the specific transcription of a gene. The phrases “operatively positioned,” “under control” or “under transcriptional control” means that the promoter is in the correct location and orientation in relation to the nucleic acid to control RNA polymerase initiation and expression of the gene. The term “expression vector or construct” means any type of genetic construct containing a nucleic acid in which part or all of the nucleic acid encoding sequence is capable of being transcribed. In some embodiments, expression includes transcription of the nucleic acid, for example, to generate a biologically-active polypeptide product or inhibitory RNA (e.g., shRNA, miRNA, miRNA inhibitor) from a transcribed gene.

The foregoing methods for packaging recombinant vectors in desired AAV capsids to produce the rAAVs of the disclosure are not meant to be limiting and other suitable methods will be apparent to the skilled artisan.

“Recombinant AAV (rAAV) vectors” of the disclosure are typically composed of, at a minimum, a transgene and its regulatory sequences, and 5′ and 3′ AAV inverted terminal repeats (ITRs). It is this recombinant AAV vector which is packaged into a capsid protein and delivered to a selected target cell. In some embodiments, the transgene is a nucleic acid sequence, heterologous to the vector sequences, which encodes a polypeptide, protein, functional RNA molecule (e.g., miRNA, miRNA inhibitor) or other gene product, of interest. The nucleic acid coding sequence is operatively linked to regulatory components in a manner which permits transgene transcription, translation, and/or expression in a cell of a target tissue.

As used herein, a “target tissue” refers to a tissue of interest, e.g., a tissue where it is desirable to deliver and/or express a transgene by AAV-mediated delivery. Target tissue may be healthy or diseased. A target tissue may be in vivo or ex vivo. In some embodiments, a target tissue contains one or more cell types present in an extracellular matrix. For example, a target tissue may comprise tumor or cancer cells and/or normal or non-transformed cells. A target tissue may be a tissue adversely affected by the improper function of a particular protein (e.g. non-functional ASPA in Canavan disease). In some embodiments, target tissue is blood, muscle, heart, pancreas and/or CNS tissue.

The AAV sequences of the vector typically comprise the cis-acting 5′ and 3′ inverted terminal repeat sequences (See, e.g., B. J. Carter, in “Handbook of Parvoviruses”, ed., P. Tijsser, CRC Press, pp. 155 168 (1990)). The ITR sequences are about 145 bp in length. Preferably, substantially the entire sequences encoding the ITRs are used in the molecule, although some degree of minor modification of these sequences is permissible. The ability to modify these ITR sequences is within the skill of the art. (See, e.g., texts such as Sambrook et al, “Molecular Cloning. A Laboratory Manual”, 2d ed., Cold Spring Harbor Laboratory, New York (1989); and K. Fisher et al., J Virol., 70:520 532 (1996)). An example of such a molecule employed in the present disclosure is a “cis-acting” plasmid containing the transgene, in which the selected transgene sequence and associated regulatory elements are flanked by the 5′ and 3′ AAV ITR sequences. The AAV ITR sequences may be obtained from any known AAV, including presently identified mammalian AAV types.

In addition to the major elements identified above for the recombinant AAV vector, the vector also includes conventional control elements necessary which are operably linked to the transgene in a manner which permits its transcription, translation and/or expression in a cell transfected with the plasmid vector or infected with the virus produced by the disclosure. As used herein, “operably linked” sequences include both expression control sequences that are contiguous with the gene of interest and expression control sequences that act in trans or at a distance to control the gene of interest.

Expression control sequences include appropriate transcription initiation, termination, promoter and enhancer sequences; efficient RNA processing signals such as splicing and polyadenylation (polyA) signals; sequences that stabilize cytoplasmic mRNA; sequences that enhance translation efficiency (i.e., Kozak consensus sequence); sequences that enhance protein stability; and when desired, sequences that enhance secretion of the encoded product. A great number of expression control sequences, including promoters which are native, constitutive, inducible and/or tissue-specific, are known in the art and may be utilized.

As used herein, a nucleic acid sequence (e.g., coding sequence) and regulatory sequences are said to be “operably” linked when they are covalently linked in such a way as to place the expression or transcription of the nucleic acid sequence under the influence or control of the regulatory sequences. If it is desired that the nucleic acid sequences be translated into a functional protein, two DNA sequences are said to be operably linked if induction of a promoter in the 5′ regulatory sequences results in the transcription of the coding sequence and if the nature of the linkage between the two DNA sequences does not (1) result in the introduction of a frame-shift mutation, (2) interfere with the ability of the promoter region to direct the transcription of the coding sequences, or (3) interfere with the ability of the corresponding RNA transcript to be translated into a protein. Thus, a promoter region would be operably linked to a nucleic acid sequence if the promoter region were capable of effecting transcription of that DNA sequence such that the resulting transcript might be translated into the desired protein or polypeptide. Similarly two or more coding regions are operably linked when they are linked in such a way that their transcription from a common promoter results in the expression of two or more proteins having been translated in frame. In some embodiments, operably linked coding sequences yield a fusion protein. In some embodiments, operably linked coding sequences yield a functional RNA (e.g., shRNA, miRNA, miRNA inhibitor).

For nucleic acids encoding proteins, a polyadenylation sequence generally is inserted following the transgene sequences and before the 3′ AAV ITR sequence. A rAAV construct useful in the present disclosure may also contain an intron, desirably located between the promoter/enhancer sequence and the transgene. One possible intron sequence is derived from SV-40, and is referred to as the SV-40 T intron sequence. Another vector element that may be used is an internal ribosome entry site (IRES). An IRES sequence is used to produce more than one polypeptide from a single gene transcript. An IRES sequence would be used to produce a protein that contain more than one polypeptide chains. Selection of these and other common vector elements are conventional and many such sequences are available [see, e.g., Sambrook et al, and references cited therein at, for example, pages 3.18 3.26 and 16.17 16.27 and Ausubel et al., Current Protocols in Molecular Biology, John Wiley & Sons, New York, 1989]. In some embodiments, a Foot and Mouth Disease Virus 2A sequence is included in polyprotein; this is a small peptide (approximately 18 amino acids in length) that has been shown to mediate the cleavage of polyproteins (Ryan, M D et al., EMBO, 1994; 4: 928-933; Mattion, N M et al., J Virology, November 1996; p. 8124-8127; Furler, S et al., Gene Therapy, 2001; 8: 864-873; and Halpin, C et al., The Plant Journal, 1999; 4: 453-459). The cleavage activity of the 2A sequence has previously been demonstrated in artificial systems including plasmids and gene therapy vectors (AAV and retroviruses) (Ryan, M D et al., EMBO, 1994; 4: 928-933; Mattion, N M et al., J Virology, November 1996; p. 8124-8127; Furler, S et al., Gene Therapy, 2001; 8: 864-873; and Halpin, C et al., The Plant Journal, 1999; 4: 453-459; de Felipe, P et al., Gene Therapy, 1999; 6: 198-208; de Felipe, P et al., Human Gene Therapy, 2000; 11: 1921-1931.; and Klump, H et al., Gene Therapy, 2001; 8: 811-817).

The precise nature of the regulatory sequences needed for gene expression in host cells may vary between species, tissues or cell types, but shall in general include, as necessary, 5′ non-transcribed and 5′ non-translated sequences involved with the initiation of transcription and translation respectively, such as a TATA box, capping sequence, CAAT sequence, enhancer elements, and the like. Especially, such 5′ non-transcribed regulatory sequences will include a promoter region that includes a promoter sequence for transcriptional control of the operably joined gene. Regulatory sequences may also include enhancer sequences or upstream activator sequences as desired. The vectors of the disclosure may optionally include 5′ leader or signal sequences. The choice and design of an appropriate vector is within the ability and discretion of one of ordinary skill in the art.

Examples of constitutive promoters include, without limitation, the retroviral Rous sarcoma virus (RSV) LTR promoter (optionally with the RSV enhancer), the cytomegalovirus (CMV) promoter (optionally with the CMV enhancer) [see, e.g., Boshart et al, Cell, 41:521-530 (1985)], the SV40 promoter, the dihydrofolate reductase promoter, the β-actin promoter, the phosphoglycerol kinase (PGK) promoter, and the EF1α promoter [Invitrogen].

Inducible promoters allow regulation of gene expression and can be regulated by exogenously supplied compounds, environmental factors such as temperature, or the presence of a specific physiological state, e.g., acute phase, a particular differentiation state of the cell, or in replicating cells only. Inducible promoters and inducible systems are available from a variety of commercial sources, including, without limitation, Invitrogen, Clontech and Ariad. Many other systems have been described and can be readily selected by one of skill in the art. Examples of inducible promoters regulated by exogenously supplied promoters include the zinc-inducible sheep metallothionine (MT) promoter, the dexamethasone (Dex)-inducible mouse mammary tumor virus (MMTV) promoter, the T7 polymerase promoter system (WO 98/10088); the ecdysone insect promoter (No et al, Proc. Natl. Acad. Sci. USA, 93:3346-3351 (1996)), the tetracycline-repressible system (Gossen et al, Proc. Natl. Acad. Sci. USA, 89:5547-5551 (1992)), the tetracycline-inducible system (Gossen et al, Science, 268:1766-1769 (1995), see also Harvey et al, Curr. Opin. Chem. Biol., 2:512-518 (1998)), the RU486-inducible system (Wang et al, Nat. Biotech., 15:239-243 (1997) and Wang et al, Gene Ther., 4:432-441 (1997)) and the rapamycin-inducible system (Magari et al, J. Clin. Invest., 100:2865-2872 (1997)). Still other types of inducible promoters which may be useful in this context are those which are regulated by a specific physiological state, e.g., temperature, acute phase, a particular differentiation state of the cell, or in replicating cells only.

In another embodiment, the native promoter for the transgene will be used. The native promoter may be preferred when it is desired that expression of the transgene should mimic the native expression. The native promoter may be used when expression of the transgene must be regulated temporally or developmentally, or in a tissue-specific manner, or in response to specific transcriptional stimuli. In a further embodiment, other native expression control elements, such as enhancer elements, polyadenylation sites or Kozak consensus sequences may also be used to mimic the native expression.

In some embodiments, the regulatory sequences impart tissue-specific gene expression capabilities. In some cases, the tissue-specific regulatory sequences bind tissue-specific transcription factors that induce transcription in a tissue specific manner. Such tissue-specific regulatory sequences (e.g., promoters, enhancers, etc.) are well known in the art. Exemplary tissue-specific regulatory sequences include, but are not limited to the following tissue specific promoters: a liver-specific thyroxin binding globulin (TBG) promoter, a insulin promoter, a glucagon promoter, a somatostatin promoter, a pancreatic polypeptide (PPY) promoter, a synapsin-1 (Syn) promoter, a creatine kinase (MCK) promoter, a mammalian desmin (DES) promoter, a α-myosin heavy chain (a-MHC) promoter, or a cardiac Troponin T (cTnT) promoter. Other exemplary promoters include Beta-actin promoter, hepatitis B virus core promoter, Sandig et al., Gene Ther., 3:1002-9 (1996); alpha-fetoprotein (AFP) promoter, Arbuthnot et al., Hum. Gene Ther., 7:1503-14 (1996)), bone osteocalcin promoter (Stein et al., Mol. Biol. Rep., 24:185-96 (1997)); bone sialoprotein promoter (Chen et al., J. Bone Miner. Res., 11:654-64 (1996)), CD2 promoter (, Hansal et al., J. Immunol., 161:1063-8 (1998); immunoglobulin heavy chain promoter; T cell receptor α-chain promoter, neuronal such as neuron-specific enolase (NSE) promoter (Andersen et al., Cell. Mol. Neurobiol., 13:503-15 (1993)), neurofilament light-chain gene promoter (Piccioli et al., Proc. Natl. Acad. Sci. USA, 88:5611-5 (1991)), and the neuron-specific vgf gene promoter (Piccioli et al., Neuron, 15:373-84 (1995)), among others which will be apparent to the skilled artisan.

In some embodiments, one or more bindings sites for one or more of miRNAs are incorporated in a transgene of a rAAV vector, to inhibit the expression of the transgene in one or more tissues of an subject harboring the transgene. The skilled artisan will appreciate that binding sites may be selected to control the expression of a trangene in a tissue specific manner. For example, binding sites for the liver-specific miR-122 may be incorporated into a transgene to inhibit expression of that transgene in the liver. The target sites in the mRNA may be in the 5′ UTR, the 3′ UTR or in the coding region. Typically, the target site is in the 3′ UTR of the mRNA. Furthermore, the transgene may be designed such that multiple miRNAs regulate the mRNA by recognizing the same or multiple sites. The presence of multiple miRNA binding sites may result in the cooperative action of multiple RISCs and provide highly efficient inhibition of expression. The target site sequence may comprise a total of 5-100, 10-60, or more nucleotides. The target site sequence may comprise at least 5 nucleotides of the sequence of a target gene binding site.

Recombinant AAV Vector: Transgene Coding Sequences

The composition of the transgene sequence of the rAAV vector will depend upon the use to which the resulting vector will be put. For example, one type of transgene sequence includes a reporter sequence, which upon expression produces a detectable signal. In another example, the trangene encodes a therapeutic protein or therapeutic functional RNA. In another example, the transgene encodes a protein or functional RNA that is intended to be used for research purposes, e.g., to create a somatic transgenic animal model harboring the transgene, e.g., to study the function of the transgene product. In another example, the transgene encodes a protein or functional RNA that is intended to be used to create an animal model of disease. Appropriate transgene coding sequences will be apparent to the skilled artisan.

Reporter sequences that may be provided in a transgene include, without limitation, DNA sequences encoding β-lactamase, β-galactosidase (LacZ), alkaline phosphatase, thymidine kinase, green fluorescent protein (GFP), chloramphenicol acetyltransferase (CAT), luciferase, and others well known in the art. When associated with regulatory elements which drive their expression, the reporter sequences, provide signals detectable by conventional means, including enzymatic, radiographic, colorimetric, fluorescence or other spectrographic assays, fluorescent activating cell sorting assays and immunological assays, including enzyme linked immunosorbent assay (ELISA), radioimmunoassay (RIA) and immunohistochemistry. For example, where the marker sequence is the LacZ gene, the presence of the vector carrying the signal is detected by assays for β-galactosidase activity. Where the transgene is green fluorescent protein or luciferase, the vector carrying the signal may be measured visually by color or light production in a luminometer. Such reporters can, for example, be useful in verifying the tissue-specific targeting capabilities and tissue specific promoter regulatory activity of an rAAV.

In some aspects, the disclosure provides rAAV vectors for use in methods of preventing or treating one or more genetic deficiencies or dysfunctions in a mammal, such as for example, a polypeptide deficiency or polypeptide excess in a mammal, and particularly for treating or reducing the severity or extent of deficiency in a human manifesting one or more of the disorders linked to a deficiency in such polypeptides in cells and tissues. The method involves administration of an rAAV vector that encodes one or more therapeutic peptides, polypeptides, siRNAs, microRNAs, antisense nucleotides, etc. in a pharmaceutically-acceptable carrier to the subject in an amount and for a period of time sufficient to treat the deficiency or disorder in the subject suffering from such a disorder.

Thus, the disclosure embraces the delivery of rAAV vectors encoding one or more peptides, polypeptides, or proteins, which are useful for the treatment or prevention of disease states in a mammalian subject. Exemplary therapeutic proteins include one or more polypeptides selected from the group consisting of growth factors, interleukins, interferons, anti-apoptosis factors, cytokines, anti-diabetic factors, anti-apoptosis agents, coagulation factors, anti-tumor factors. Other non-limiting examples of therapeutic proteins include BDNF, CNTF, CSF, EGF, FGF, G-SCF, GM-CSF, gonadotropin, IFN, IFG-1, M-CSF, NGF, PDGF, PEDF, TGF, VEGF, TGF-B2, TNF, prolactin, somatotropin, XIAP1, IL-1, IL-2, IL-3, IL-4, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-10(187A), viral IL-10, IL-11, IL-12, IL-13, IL-14, IL-15, IL-16 IL-17, and IL-18.

The rAAV vectors may comprise a gene to be transferred to a subject to treat a disease associated with reduced expression, lack of expression or dysfunction of the gene. In some embodiments, the dysfunctional gene is ASPA and the disease is Canavan disease.

Exemplary genes and associated disease states include, but are not limited to: glucose-6-phosphatase, associated with glycogen storage deficiency type 1A; phosphoenolpyruvate-carboxykinase, associated with Pepck deficiency; galactose-1 phosphate uridyl transferase, associated with galactosemia; phenylalanine hydroxylase, associated with phenylketonuria; branched chain alpha-ketoacid dehydrogenase, associated with Maple syrup urine disease; fumarylacetoacetate hydrolase, associated with tyrosinemia type 1; methylmalonyl-CoA mutase, associated with methylmalonic acidemia; medium chain acyl CoA dehydrogenase, associated with medium chain acetyl CoA deficiency; omithine transcarbamylase, associated with omithine transcarbamylase deficiency; argininosuccinic acid synthetase, associated with citrullinemia; low density lipoprotein receptor protein, associated with familial hypercholesterolemia; UDP-glucouronosyltransferase, associated with Crigler-Najjar disease; adenosine deaminase, associated with severe combined immunodeficiency disease; hypoxanthine guanine phosphoribosyl transferase, associated with Gout and Lesch-Nyan syndrome; biotinidase, associated with biotinidase deficiency; beta-glucocerebrosidase, associated with Gaucher disease; beta-glucuronidase, associated with Sly syndrome; peroxisome membrane protein 70 kDa, associated with Zellweger syndrome; porphobilinogen deaminase, associated with acute intermittent porphyria; alpha-1 antitrypsin for treatment of alpha-1 antitrypsin deficiency (emphysema); erythropoietin for treatment of anemia due to thalassemia or to renal failure; vascular endothelial growth factor, angiopoietin-1, and fibroblast growth factor for the treatment of ischemic diseases; thrombomodulin and tissue factor pathway inhibitor for the treatment of occluded blood vessels as seen in, for example, atherosclerosis, thrombosis, or embolisms; aromatic amino acid decarboxylase (AADC), and tyrosine hydroxylase (TH) for the treatment of Parkinson's disease; the beta adrenergic receptor, anti-sense to, or a mutant form of, phospholamban, the sarco(endo)plasmic reticulum adenosine triphosphatase-2 (SERCA2), and the cardiac adenylyl cyclase for the treatment of congestive heart failure; a tumor suppessor gene such as p53 for the treatment of various cancers; a cytokine such as one of the various interleukins for the treatment of inflammatory and immune disorders and cancers; dystrophin or minidystrophin and utrophin or miniutrophin for the treatment of muscular dystrophies; and, insulin for the treatment of diabetes.

In some embodiments, The rAAV vectors may comprise a gene encoding an antigen-binding protein, such as an immunoglobulin heavy chain or light chain or fragment thereof, e.g., that may be used for therapeutic purposes. In some embodiments, the protein is a single chain Fv fragment or Fv-Fc fragment. Accordingly, in some embodiments, the rAAV can be used to infect cells of a target tissue (e.g., muscle tissue) so as to engineer cells of the tissue to express an antigen-binding protein, such as an antibody or fragment thereof. In some embodiments, to generate rAAVs that express the antibodies or antigen binding fragments, cDNAs engineered to express such proteins will be sucloned into an appropriate plasmid backbone and packaged into an rAAV.

The rAAVs of the disclosure can be used to restore the expression of genes that are reduced in expression, silenced, or otherwise dysfunctional in a subject (e.g., a tumor suppressor that has been silenced in a subject having cancer). The rAAVs of the disclosure can also be used to knockdown the expression of genes that are aberrantly expressed in a subject (e.g., an oncogene that is expressed in a subject having cancer). In some embodiments, an rAAV vector comprising a nucleic acid encoding a gene product associated with cancer (e.g., tumor suppressors) may be used to treat the cancer, by administering a rAAV harboring the rAAV vector to a subject having the cancer. In some embodiments, an rAAV vector comprising a nucleic acid encoding a small interfering nucleic acid (e.g., shRNAs, miRNAs) that inhibits the expression of a gene product associated with cancer (e.g., oncogenes) may be used to treat the cancer, by administering a rAAV harboring the rAAV vector to a subject having the cancer. In some embodiments, an rAAV vector comprising a nucleic acid encoding a gene product associated with cancer (or a functional RNA that inhibits the expression of a gene associated with cancer) may be used for research purposes, e.g., to study the cancer or to identify therapeutics that treat the cancer. The following is a non-limiting list of exemplary genes known to be associated with the development of cancer (e.g., oncogenes and tumor suppressors): AARS, ABCB1, ABCC4, ABI2, ABL1, ABL2, ACK1, ACP2, ACY1, ADSL, AK1, AKR1C2, AKT1, ALB, ANPEP, ANXA5, ANXA7, AP2M1, APC, ARHGAP5, ARHGEF5, ARID4A, ASNS, ATF4, ATM, ATP5B, ATP5O, AXL, BARD1, BAX, BCL2, BHLHB2, BLMH, BRAF, BRCA1, BRCA2, BTK, CANX, CAP1, CAPN1, CAPNS1, CAV1, CBFB, CBLB, CCL2, CCND1, CCND2, CCND3, CCNE1, CCT5, CCYR61, CD24, CD44, CD59, CDC20, CDC25, CDC25A, CDC25B, CDC2L5, CDK10, CDK4, CDK5, CDK9, CDKL1, CDKN1A, CDKN1B, CDKN1C, CDKN2A, CDKN2B, CDKN2D, CEBPG, CENPC1, CGRRF1, CHAF1A, CIB1, CKMT1, CLK1, CLK2, CLK3, CLNS1A, CLTC, COL1A1, COL6A3, COX6C, COX7A2, CRAT, CRHR1, CSF1R, CSK, CSNK1G2, CTNNA1, CTNNB1, CTPS, CTSC, CTSD, CUL1, CYR61, DCC, DCN, DDX10, DEK, DHCR7, DHRS2, DHX8, DLG3, DVL1, DVL3, E2F1, E2F3, E2F5, EGFR, EGR1, EIF5, EPHA2, ERBB2, ERBB3, ERBB4, ERCC3, ETV1, ETV3, ETV6, F2R, FASTK, FBN1, FBN2, FES, FGFR1, FGR, FKBP8, FN1, FOS, FOSL1, FOSL2, FOXG1A, FOXO1A, FRAP1, FRZB, FTL, FZD2, FZD5, FZD9, G22P1, GAS6, GCN5L2, GDF15, GNA13, GNAS, GNB2, GNB2L1, GPR39, GRB2, GSK3A, GSPT1, GTF2I, HDAC1, HDGF, HMMR, HPRT1, HRB, HSPA4, HSPA5, HSPA8, HSPB1, HSPH1, HYAL1, HYOU1, ICAM1, ID1, ID2, IDUA, IER3, IFITM1, IGF1R, IGF2R, IGFBP3, IGFBP4, IGFBP5, IL1B, ILK, ING1, IRF3, ITGA3, ITGA6, ITGB4, JAK1, JARID1A, JUN, JUNB, JUND, K-ALPHA-1, KIT, KITLG, KLK10, KPNA2, KRAS2, KRT18, KRT2A, KRT9, LAMB1, LAMP2, LCK, LCN2, LEP, LITAF, LRPAP1, LTF, LYN, LZTR1, MADH1, MAP2K2, MAP3K8, MAPK12, MAPK13, MAPKAPK3, MAPRE1, MARS, MAS1, MCC, MCM2, MCM4, MDM2, MDM4, MET, MGST1, MICB, MLLT3, MME, MMP1, MMP14, MMP17, MMP2, MNDA, MSH2, MSH6, MT3, MYB, MYBL1, MYBL2, MYC, MYCL1, MYCN, MYD88, MYL9, MYLK, NEO1, NF1, NF2, NFKB1, NFKB2, NFSF7, NID, NINJ1, NMBR, NME1, NME2, NME3, NOTCH1, NOTCH2, NOTCH4, NPM1, NQO1, NR1D1, NR2F1, NR2F6, NRAS, NRG1, NSEP1, OSM, PA2G4, PABPC1, PCNA, PCTK1, PCTK2, PCTK3, PDGFA, PDGFB, PDGFRA, PDPK1, PEA15, PFDN4, PFDN5, PGAM1, PHB, PIK3CA, PIK3CB, PIK3CG, PIM1, PKM2, PKMYT1, PLK2, PPARD, PPARG, PPIH, PPP1CA, PPP2R5A, PRDX2, PRDX4, PRKAR1A, PRKCBP1, PRNP, PRSS15, PSMA1, PTCH, PTEN, PTGS1, PTMA, PTN, PTPRN, RAB5A, RAC1, RAD50, RAF1, RALBP1, RAP1A, RARA, RARB, RASGRF1, RB1, RBBP4, RBL2, REA, REL, RELA, RELB, RET, RFC2, RGS19, RHOA, RHOB, RHOC, RHOD, RIPK1, RPN2, RPS6KB1, RRM1, SARS, SELENBP1, SEMA3C, SEMA4D, SEPP1, SERPINH1, SFN, SFPQ, SFRS7, SHB, SHH, SIAH2, SIVA, SIVA TP53, SKI, SKIL, SLC16A1, SLC1A4, SLC20A1, SMO, SMPD1, SNAI2, SND1, SNRPB2, SOCS1, SOCS3, SOD1, SORT1, SPINT2, SPRY2, SRC, SRPX, STAT1, STAT2, STAT3, STAT5B, STC1, TAF1, TBL3, TBRG4, TCF1, TCF7L2, TFAP2C, TFDP1, TFDP2, TGFA, TGFB1, TGFBI, TGFBR2, TGFBR3, THBS1, TIE, TIMP1, TIMP3, TJP1, TK1, TLE1, TNF, TNFRSF10A, TNFRSF10B, TNFRSF1A, TNFRSF1B, TNFRSF6, TNFSF7, TNK1, TOB1, TP53, TP53BP2, TP53I3, TP73, TPBG, TPT1, TRADD, TRAM1, TRRAP, TSG101, TUFM, TXNRD1, TYRO3, UBC, UBE2L6, UCHL1, USP7, VDAC1, VEGF, VHL, VIL2, WEE1, WNT1, WNT2, WNT2B, WNT3, WNT5A, WT1, XRCC1, YES1, YWHAB, YWHAZ, ZAP70, and ZNF9.

In some embodiments, rAAV vectors comprising a transgene encoding a tumor suppressor protein are useful for the treatment of cancer. As used herein, the term “tumor suppressor protein” refers to protein that inhibits the formation, development or maintainance of a tumor. In some embodiments, a tumor suppressor protein suppresses regulation of the cell cycle and/or promotes apoptosis. Loss or dysfunction of tumor suppressor proteins is a key step in the development of cancer. Accordingly, expression of tumor suppressor proteins inhibits or slows the growth of cancerous tumors and may therefore be a viable therapeutic strategy for treatment of cancer. In some embodiments, the tumor suppressor protein is a secreted tumor suppressor protein. Non-limiting examples of secreted tumor suppressor proteins include IGFBP7, SRPX, and others disclosed for example in Min Zhao, Jingchun Sun, Zhongming Zhao (2013) TSGene: a web resource for tumor suppressor genes. Nucleic Acids Research, 41: D970-D976.

A rAAV vector may comprise as a transgene, a nucleic acid encoding a protein or functional RNA that modulates apoptosis. The following is a non-limiting list of genes associated with apoptosis and nucleic acids encoding the products of these genes and their homologues and encoding small interfering nucleic acids (e.g., shRNAs, miRNAs) that inhibit the expression of these genes and their homologues are useful as transgenes in certain embodiments of the disclosure: RPS27A, ABL1, AKT1, APAF1, BAD, BAG1, BAG3, BAG4, BAK1, BAX, BCL10, BCL2, BCL2A1, BCL2L1, BCL2L10, BCL2L11, BCL2L12, BCL2L13, BCL2L2, BCLAF1, BFAR, BID, BIK, NAIP, BIRC2, BIRC3, XIAP, BIRC5, BIRC6, BIRC7, BIRC8, BNIP1, BNIP2, BNIP3, BNIP3L, BOK, BRAF, CARD10, CARD11, NLRC4, CARD14, NOD2, NOD1, CARD6, CARD8, CARD9, CASP1, CASP10, CASP14, CASP2, CASP3, CASP4, CASP5, CASP6, CASP7, CASP8, CASP9, CFLAR, CIDEA, CIDEB, CRADD, DAPK1, DAPK2, DFFA, DFFB, FADD, GADD45A, GDNF, HRK, IGF1R, LTA, LTBR, MCL1, NOL3, PYCARD, RIPK1, RIPK2, TNF, TNFRSF10A, TNFRSF10B, TNFRSF10C, TNFRSF10D, TNFRSF11B, TNFRSF12A, TNFRSF14, TNFRSF19, TNFRSF1A, TNFRSF1B, TNFRSF21, TNFRSF25, CD40, FAS, TNFRSF6B, CD27, TNFRSF9, TNFSF10, TNFSF14, TNFSF18, CD4OLG, FASLG, CD70, TNFSF8, TNFSF9, TP53, TP53BP2, TP73, TP63, TRADD, TRAF1, TRAF2, TRAF3, TRAF4, and TRAF5.

The skilled artisan will also realize that in the case of transgenes encoding proteins or polypeptides, that mutations that results in conservative amino acid substitutions may be made in a transgene to provide functionally equivalent variants, or homologs of a protein or polypeptide. In some aspects the disclosure embraces sequence alterations that result in conservative amino acid substitution of a transgene. In some embodiments, the transgene comprises a gene having a dominant negative mutation. For example, a transgene may express a mutant protein that interacts with the same elements as a wild-type protein, and thereby blocks some aspect of the function of the wild-type protein.

Useful transgene products also include miRNAs. miRNAs and other small interfering nucleic acids regulate gene expression via target RNA transcript cleavage/degradation or translational repression of the target messenger RNA (mRNA). miRNAs are natively expressed, typically as final 19-25 non-translated RNA products. miRNAs exhibit their activity through sequence-specific interactions with the 3′ untranslated regions (UTR) of target mRNAs. These endogenously expressed miRNAs form hairpin precursors which are subsequently processed into a miRNA duplex, and further into a “mature” single stranded miRNA molecule. This mature miRNA guides a multiprotein complex, miRISC, which identifies target site, e.g., in the 3′ UTR regions, of target mRNAs based upon their complementarity to the mature miRNA.

The following non-limiting list of miRNA genes, and their homologues, are useful as transgenes or as targets for small interfering nucleic acids encoded by transgenes (e.g., miRNA sponges, antisense

A miRNA inhibits the function of the mRNAs it targets and, as a result, inhibits expression of the polypeptides encoded by the mRNAs. Thus, blocking (partially or totally) the activity of the miRNA (e.g., silencing the miRNA) can effectively induce, or restore, expression of a polypeptide whose expression is inhibited (derepress the polypeptide). In one embodiment, derepression of polypeptides encoded by mRNA targets of a miRNA is accomplished by inhibiting the miRNA activity in cells through any one of a variety of methods. For example, blocking the activity of a miRNA can be accomplished by hybridization with a small interfering nucleic acid (e.g., antisense oligonucleotide, miRNA sponge, TuD RNA) that is complementary, or substantially complementary to, the miRNA, thereby blocking interaction of the miRNA with its target mRNA. As used herein, an small interfering nucleic acid that is substantially complementary to a miRNA is one that is capable of hybridizing with a miRNA, and blocking the miRNA's activity. In some embodiments, an small interfering nucleic acid that is substantially complementary to a miRNA is an small interfering nucleic acid that is complementary with the miRNA at all but 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, or 18 bases. In some embodiments, an small interfering nucleic acid sequence that is substantially complementary to a miRNA, is an small interfering nucleic acid sequence that is complementary with the miRNA at, at least, one base.

A “miRNA Inhibitor” is an agent that blocks miRNA function, expression and/or processing. For instance, these molecules include but are not limited to microRNA specific antisense, microRNA sponges, tough decoy RNAs (TuD RNAs) and microRNA oligonucleotides (double-stranded, hairpin, short oligonucleotides) that inhibit miRNA interaction with a Drosha complex. MicroRNA inhibitors can be expressed in cells from a transgenes of a rAAV vector, as discussed above. MicroRNA sponges specifically inhibit miRNAs through a complementary heptameric seed sequence (Ebert, M.S. Nature Methods, Epub Aug. 12, 2007;). In some embodiments, an entire family of miRNAs can be silenced using a single sponge sequence. TuD RNAs achieve efficient and long-term-suppression of specific miRNAs in mammalian cells (See, e.g., Takeshi Haraguchi, et al., Nucleic Acids Research, 2009, Vol. 37, No. 6 e43, the contents of which relating to TuD RNAs are incorporated herein by reference). Other methods for silencing miRNA function (derepression of miRNA targets) in cells will be apparent to one of ordinary skill in the art.

In some embodiments, the cloning capacity of the recombinant RNA vector may limited and a desired coding sequence may require the complete replacement of the virus's 4.8 kilobase genome. Large genes may, therefore, not be suitable for use in a standard recombinant AAV vector, in some cases. The skilled artisan will appreciate that options are available in the art for overcoming a limited coding capacity. For example, the AAV ITRs of two genomes can anneal to form head to tail concatamers, almost doubling the capacity of the vector. Insertion of splice sites allows for the removal of the ITRs from the transcript. Other options for overcoming a limited cloning capacity will be apparent to the skilled artisan.

Somatic Transgenic Animal Models Produced Using rAAV-Based Gene Transfer

The disclosure also involves the production of somatic transgenic animal models of disease using recombinant Adeno-Associated Virus (rAAV) based methods. The methods are based, at least in part, on the observation that AAV serotypes and variants thereof mediate efficient and stable gene transfer in a tissue specific manner in adult animals. The rAAV elements (capsid, promoter, transgene products) are combined to achieve somatic transgenic animal models that express a stable transgene in a time and tissue specific manner. The somatic transgenic animal produced by the methods of the disclosure can serve as useful models of human disease, pathological state, and/or to characterize the effects of gene for which the function (e.g., tissue specific, disease role) is unknown or not fully understood. For example, an animal (e.g., mouse) can be infected at a distinct developmental stage (e.g., age) with a rAAV comprising a capsid having a specific tissue targeting capability (e.g., liver, heart, pancreas, CNS) and a transgene having a tissue specific promoter driving expression of a gene involved in disease. Upon infection, the rAAV infects distinct cells of the target tissue and produces the product of the transgene.

In some embodiments, the sequence of the coding region of a transgene is modified. The modification may alter the function of the product encoded by the transgene. The effect of the modification can then be studied in vivo by generating a somatic transgenic animal model using the methods disclosed herein. In some embodiments, modification of the sequence of coding region is a nonsense mutation that results in a fragment (e.g., a truncated version). In other cases, the modification is a missense mutation that results in an amino acid substitution. Other modifications are possible and will be apparent to the skilled artisan.

In some embodiments, the transgene causes a pathological state. A transgene that causes a pathological state is a gene whose product has a role in a disease or disorder (e.g., causes the disease or disorder, makes the animal susceptible to the disease or disorder) and/or may induce the disease or disorder in the animal. The animal can then be observed to evaluate any number of aspects of the disease (e.g., progression, response to treatment, etc). These examples are not meant to be limiting, other aspects and examples are disclosed herein and described in more detail below.

The disclosure in some aspects, provide methods for producing somatic transgenic animal models through the targeted destruction of specific cell types. For example, models of type 1 diabetes can be produced by the targeted destruction of pancreatic Beta-islets. In other examples, the targeted destruction of specific cell types can be used to evaluate the role of specific cell types on human disease. In this regard, transgenes that encode cellular toxins (e.g., diphtheria toxin A (DTA)) or pro-apoptotic genes (NTR, Box, etc.) can be useful as transgenes for functional ablation of specific cell types. Other exemplary transgenes, whose products kill cells are embraced by the methods disclosed herein and will be apparent to one of ordinary skill in the art.

The disclosure in some aspects, provides methods for producing somatic transgenic animal models to study the long-term effects of over-expression or knockdown of genes. The long term over expression or knockdown (e.g., by shRNA, miRNA, miRNA inhibitor, etc.) of genes in specific target tissues can disturb normal metabolic balance and establish a pathological state, thereby producing an animal model of a disease, such as, for example, cancer. The disclosure in some aspects, provides methods for producing somatic transgenic animal models to study the long-term effects of over-expression or knockdown of gene of potential oncogenes and other genes to study tumorigenesis and gene function in the targeted tissues. Useful transgene products include proteins that are known to be associated with cancer and small interfering nucleic acids inhibiting the expression of such proteins. Other suitable transgenes may be readily selected by one of skill in the art provided that they are useful for creating animal models of tissue-specific pathological state and/or disease.

Recombinant AAV Administration Methods

The rAAVs may be delivered to a subject in compositions according to any appropriate methods known in the art. The rAAV, preferably suspended in a physiologically compatible carrier (i.e., in a composition), may be administered to a subject, i.e. host animal, such as a human, mouse, rat, cat, dog, sheep, rabbit, horse, cow, goat, pig, guinea pig, hamster, chicken, turkey, or a non-human primate (e.g, Macaque). In some embodiments a host animal does not include a human.

Delivery of the rAAVs to a mammalian subject may be by, for example, intramuscular injection or by administration into the bloodstream of the mammalian subject. Administration into the bloodstream may be by injection into a vein, an artery, or any other vascular conduit. In some embodiments, the rAAVs are administered into the bloodstream by way of isolated limb perfusion, a technique well known in the surgical arts, the method essentially enabling the artisan to isolate a limb from the systemic circulation prior to administration of the rAAV virions. A variant of the isolated limb perfusion technique, described in U.S. Pat. No. 6,177,403, can also be employed by the skilled artisan to administer the virions into the vasculature of an isolated limb to potentially enhance transduction into muscle cells or tissue. Moreover, in certain instances, it may be desirable to deliver the virions to the CNS of a subject. By “CNS” is meant all cells and tissue of the brain and spinal cord of a vertebrate. Thus, the term includes, but is not limited to, neuronal cells, glial cells, astrocytes, cereobrospinal fluid (CSF), interstitial spaces, bone, cartilage and the like. Recombinant AAVs may be delivered directly to the CNS or brain by injection into, e.g., the ventricular region, as well as to the striatum (e.g., the caudate nucleus or putamen of the striatum), spinal cord and neuromuscular junction, or cerebellar lobule, with a needle, catheter or related device, using neurosurgical techniques known in the art, such as by stereotactic injection (see, e.g., Stein et al., J Virol 73:3424-3429, 1999; Davidson et al., PNAS 97:3428-3432, 2000; Davidson et al., Nat. Genet. 3:219-223, 1993; and Alisky and Davidson, Hum. Gene Ther. 11:2315-2329, 2000). Recombinant AAVs may also be delivered indirectly to the CNS, for example by intravenous injection.

The compositions of the disclosure may comprise an rAAV alone, or in combination with one or more other viruses (e.g., a second rAAV encoding having one or more different transgenes). In some embodiments, a composition comprises 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or more different rAAVs each having one or more different transgenes.

Suitable carriers may be readily selected by one of skill in the art in view of the indication for which the rAAV is directed. For example, one suitable carrier includes saline, which may be formulated with a variety of buffering solutions (e.g., phosphate buffered saline). Other exemplary carriers include sterile saline, lactose, sucrose, calcium phosphate, gelatin, dextran, agar, pectin, peanut oil, sesame oil, and water. The selection of the carrier is not a limitation of the present disclosure.

Optionally, the compositions of the disclosure may contain, in addition to the rAAV and carrier(s), other conventional pharmaceutical ingredients, such as preservatives, or chemical stabilizers. Suitable exemplary preservatives include chlorobutanol, potassium sorbate, sorbic acid, sulfur dioxide, propyl gallate, the parabens, ethyl vanillin, glycerin, phenol, and parachlorophenol. Suitable chemical stabilizers include gelatin and albumin.

The rAAVS are administered in sufficient amounts to transfect the cells of a desired tissue and to provide sufficient levels of gene transfer and expression without undue adverse effects. Conventional and pharmaceutically acceptable routes of administration include, but are not limited to, direct delivery to the selected organ (e.g., intraportal delivery to the liver), oral, inhalation (including intranasal and intratracheal delivery), intraocular, intravenous, intramuscular, subcutaneous, intradermal, intratumoral, and other parental routes of administration. Routes of administration may be combined, if desired.

The dose of rAAV virions required to achieve a particular “therapeutic effect,” e.g., the units of dose in genome copies/per kilogram of body weight (GC/kg), will vary based on several factors including, but not limited to: the route of rAAV virion administration, the level of gene or RNA expression required to achieve a therapeutic effect, the specific disease or disorder being treated, and the stability of the gene or RNA product. One of skill in the art can readily determine a rAAV virion dose range to treat a patient having a particular disease or disorder based on the aforementioned factors, as well as other factors that are well known in the art.

An effective amount of an rAAV is an amount sufficient to target infect an animal, target a desired tissue. In some embodiments, an effective amount of an rAAV is an amount sufficient to produce a stable somatic transgenic animal model. The effective amount will depend primarily on factors such as the species, age, weight, health of the subject, and the tissue to be targeted, and may thus vary among animal and tissue. For example, a effective amount of the rAAV is generally in the range of from about 1 ml to about 100 ml of solution containing from about 10⁹ to 10¹⁶ genome copies. In some cases, a dosage between about 10¹¹ to 10¹² rAAV genome copies is appropriate. In certain embodiments, 10¹² rAAV genome copies is effective to target heart, liver, and pancreas or CNS tissues. In some cases, stable transgenic animals are produced by multiple doses of an rAAV.

In some embodiments, rAAV compositions are formulated to reduce aggregation of AAV particles in the composition, particularly where high rAAV concentrations are present (e.g., ˜10¹³ GC/ml or more). Methods for reducing aggregation of rAAVs are well known in the art and, include, for example, addition of surfactants, pH adjustment, salt concentration adjustment, etc. (See, e.g., Wright F R, et al., Molecular Therapy (2005) 12, 171-178, the contents of which are incorporated herein by reference.)

Formulation of pharmaceutically-acceptable excipients and carrier solutions is well-known to those of skill in the art, as is the development of suitable dosing and treatment regimens for using the particular compositions described herein in a variety of treatment regimens.

Typically, these formulations may contain at least about 0.1% of the active compound or more, although the percentage of the active ingredient(s) may, of course, be varied and may conveniently be between about 1 or 2% and about 70% or 80% or more of the weight or volume of the total formulation. Naturally, the amount of active compound in each therapeutically-useful composition may be prepared is such a way that a suitable dosage will be obtained in any given unit dose of the compound. Factors such as solubility, bioavailability, biological half-life, route of administration, product shelf life, as well as other pharmacological considerations will be contemplated by one skilled in the art of preparing such pharmaceutical formulations, and as such, a variety of dosages and treatment regimens may be desirable.

In certain circumstances it will be desirable to deliver the rAAV-based therapeutic constructs in suitably formulated pharmaceutical compositions disclosed herein either subcutaneously, intraopancreatically, intranasally, parenterally, intravenously, intramuscularly, intrathecally, or orally, intraperitoneally, or by inhalation. In some embodiments, the administration modalities as described in U.S. Pat. Nos. 5,543,158; 5,641,515 and 5,399,363 (each specifically incorporated herein by reference in its entirety) may be used to deliver rAAVs. In some embodiments, a preferred mode of administration is by portal vein injection.

The pharmaceutical forms suitable for injectable use include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. Dispersions may also be prepared in glycerol, liquid polyethylene glycols, and mixtures thereof and in oils. Under ordinary conditions of storage and use, these preparations contain a preservative to prevent the growth of microorganisms. In many cases the form is sterile and fluid to the extent that easy syringability exists. It must be stable under the conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms, such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g., glycerol, propylene glycol, and liquid polyethylene glycol, and the like), suitable mixtures thereof, and/or vegetable oils. Proper fluidity may be maintained, for example, by the use of a coating, such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. The prevention of the action of microorganisms can be brought about by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, thimerosal, and the like. In many cases, it will be preferable to include isotonic agents, for example, sugars or sodium chloride. Prolonged absorption of the injectable compositions can be brought about by the use in the compositions of agents delaying absorption, for example, aluminum monostearate and gelatin. For administration of an injectable aqueous solution, for example, the solution may be suitably buffered, if necessary, and the liquid diluent first rendered isotonic with sufficient saline or glucose. These particular aqueous solutions are especially suitable for intravenous, intramuscular, subcutaneous and intraperitoneal administration. In this connection, a sterile aqueous medium that can be employed will be known to those of skill in the art. For example, one dosage may be dissolved in 1 ml of isotonic NaCl solution and either added to 1000 ml of hypodermoclysis fluid or injected at the proposed site of infusion, (see for example, “Remington's Pharmaceutical Sciences” 15th Edition, pages 1035-1038 and 1570-1580). Some variation in dosage will necessarily occur depending on the condition of the host. The person responsible for administration will, in any event, determine the appropriate dose for the individual host.

Sterile injectable solutions are prepared by incorporating the active rAAV in the required amount in the appropriate solvent with various of the other ingredients enumerated herein, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the various sterilized active ingredients into a sterile vehicle which contains the basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, the preferred methods of preparation are vacuum-drying and freeze-drying techniques which yield a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered solution thereof.

The rAAV compositions disclosed herein may also be formulated in a neutral or salt form. Pharmaceutically-acceptable salts, include the acid addition salts (formed with the free amino groups of the protein) and which are formed with inorganic acids such as, for example, hydrochloric or phosphoric acids, or such organic acids as acetic, oxalic, tartaric, mandelic, and the like. Salts formed with the free carboxyl groups can also be derived from inorganic bases such as, for example, sodium, potassium, ammonium, calcium, or ferric hydroxides, and such organic bases as isopropylamine, trimethylamine, histidine, procaine and the like. Upon formulation, solutions will be administered in a manner compatible with the dosage formulation and in such amount as is therapeutically effective. The formulations are easily administered in a variety of dosage forms such as injectable solutions, drug-release capsules, and the like.

As used herein, “carrier” includes any and all solvents, dispersion media, vehicles, coatings, diluents, antibacterial and antifungal agents, isotonic and absorption delaying agents, buffers, carrier solutions, suspensions, colloids, and the like. The use of such media and agents for pharmaceutical active substances is well known in the art. Supplementary active ingredients can also be incorporated into the compositions. The phrase “pharmaceutically-acceptable” refers to molecular entities and compositions that do not produce an allergic or similar untoward reaction when administered to a host.

Delivery vehicles such as liposomes, nanocapsules, microparticles, microspheres, lipid particles, vesicles, and the like, may be used for the introduction of the compositions of the present disclosure into suitable host cells. In particular, the rAAV vector delivered trangenes may be formulated for delivery either encapsulated in a lipid particle, a liposome, a vesicle, a nanosphere, or a nanoparticle or the like.

Such formulations may be preferred for the introduction of pharmaceutically acceptable formulations of the nucleic acids or the rAAV constructs disclosed herein. The formation and use of liposomes is generally known to those of skill in the art. Recently, liposomes were developed with improved serum stability and circulation half-times (U.S. Pat. No. 5,741,516). Further, various methods of liposome and liposome like preparations as potential drug carriers have been described (U.S. Pat. Nos. 5,567,434; 5,552,157; 5,565,213; 5,738,868 and 5,795,587).

Liposomes have been used successfully with a number of cell types that are normally resistant to transfection by other procedures. In addition, liposomes are free of the DNA length constraints that are typical of viral-based delivery systems. Liposomes have been used effectively to introduce genes, drugs, radiotherapeutic agents, viruses, transcription factors and allosteric effectors into a variety of cultured cell lines and animals. In addition, several successful clinical trails examining the effectiveness of liposome-mediated drug delivery have been completed.

Liposomes are formed from phospholipids that are dispersed in an aqueous medium and spontaneously form multilamellar concentric bilayer vesicles (also termed multilamellar vesicles (MLVs). MLVs generally have diameters of from 25 nm to 4 μm. Sonication of MLVs results in the formation of small unilamellar vesicles (SUVs) with diameters in the range of 200 to 500.ANG., containing an aqueous solution in the core.

Alternatively, nanocapsule formulations of the rAAV may be used. Nanocapsules can generally entrap substances in a stable and reproducible way. To avoid side effects due to intracellular polymeric overloading, such ultrafine particles (sized around 0.1 μm) should be designed using polymers able to be degraded in vivo. Biodegradable polyalkyl-cyanoacrylate nanoparticles that meet these requirements are contemplated for use.

In addition to the methods of delivery described above, the following techniques are also contemplated as alternative methods of delivering the rAAV compositions to a host. Sonophoresis (ie., ultrasound) has been used and described in U.S. Pat. No. 5,656,016 as a device for enhancing the rate and efficacy of drug permeation into and through the circulatory system. Other drug delivery alternatives contemplated are intraosseous injection (U.S. Pat. No. 5,779,708), microchip devices (U.S. Pat. No. 5,797,898), ophthalmic formulations (Bourlais et al., 1998), transdermal matrices (U.S. Pat. Nos. 5,770,219 and 5,783,208) and feedback-controlled delivery (U.S. Pat. No. 5,697,899).

Kits and Related Compositions

The agents described herein may, in some embodiments, be assembled into pharmaceutical or diagnostic or research kits to facilitate their use in therapeutic, diagnostic or research applications. A kit may include one or more containers housing the components of the disclosure and instructions for use. Specifically, such kits may include one or more agents described herein, along with instructions describing the intended application and the proper use of these agents. In certain embodiments agents in a kit may be in a pharmaceutical formulation and dosage suitable for a particular application and for a method of administration of the agents. Kits for research purposes may contain the components in appropriate concentrations or quantities for running various experiments.

The kit may be designed to facilitate use of the methods described herein by researchers and can take many forms. Each of the compositions of the kit, where applicable, may be provided in liquid form (e.g., in solution), or in solid form, (e.g., a dry powder). In certain cases, some of the compositions may be constitutable or otherwise processable (e.g., to an active form), for example, by the addition of a suitable solvent or other species (for example, water or a cell culture medium), which may or may not be provided with the kit. As used herein, “instructions” can define a component of instruction and/or promotion, and typically involve written instructions on or associated with packaging of the disclosure. Instructions also can include any oral or electronic instructions provided in any manner such that a user will clearly recognize that the instructions are to be associated with the kit, for example, audiovisual (e.g., videotape, DVD, etc.), Internet, and/or web-based communications, etc. The written instructions may be in a form prescribed by a governmental agency regulating the manufacture, use or sale of pharmaceuticals or biological products, which instructions can also reflects approval by the agency of manufacture, use or sale for animal administration.

The kit may contain any one or more of the components described herein in one or more containers. As an example, in one embodiment, the kit may include instructions for mixing one or more components of the kit and/or isolating and mixing a sample and applying to a subject. The kit may include a container housing agents described herein. The agents may be in the form of a liquid, gel or solid (powder). The agents may be prepared sterilely, packaged in syringe and shipped refrigerated. Alternatively it may be housed in a vial or other container for storage. A second container may have other agents prepared sterilely. Alternatively the kit may include the active agents premixed and shipped in a syringe, vial, tube, or other container. The kit may have one or more or all of the components required to administer the agents to an animal, such as a syringe, topical application devices, or iv needle tubing and bag, particularly in the case of the kits for producing specific somatic animal models.

In some cases, the methods involve transfecting cells with total cellular DNAs isolated from the tissues that potentially harbor proviral AAV genomes at very low abundance and supplementing with helper virus function (e.g., adenovirus) to trigger and/or boost AAV rep and cap gene transcription in the transfected cell. In some cases, RNA from the transfected cells provides a template for RT-PCR amplification of cDNA and the detection of novel AAVs. In cases where cells are transfected with total cellular DNAs isolated from the tissues that potentially harbor proviral AAV genomes, it is often desirable to supplement the cells with factors that promote AAV gene transcription. For example, the cells may also be infected with a helper virus, such as an Adenovirus or a Herpes Virus. In a specific embodiment, the helper functions are provided by an adenovirus. The adenovirus may be a wild-type adenovirus, and may be of human or non-human origin, preferably non-human primate (NHP) origin. Similarly adenoviruses known to infect non-human animals (e.g., chimpanzees, mouse) may also be employed in the methods of the disclosure (See, e.g., U.S. Pat. No. 6,083,716). In addition to wild-type adenoviruses, recombinant viruses or non-viral vectors (e.g., plasmids, episomes, etc.) carrying the necessary helper functions may be utilized. Such recombinant viruses are known in the art and may be prepared according to published techniques. See, e.g., U.S. Pat. No. 5,871,982 and U.S. Pat. No. 6,251,677, which describe a hybrid Ad/AAV virus. A variety of adenovirus strains are available from the American Type Culture Collection, Manassas, Va., or available by request from a variety of commercial and institutional sources. Further, the sequences of many such strains are available from a variety of databases including, e.g., PubMed and GenBank.

Cells may also be transfected with a vector (e.g., helper vector) which provides helper functions to the AAV. The vector providing helper functions may provide adenovirus functions, including, e.g., E1a, E1b, E2a, E4ORF6. The sequences of adenovirus gene providing these functions may be obtained from any known adenovirus serotype, such as serotypes 2, 3, 4, 7, 12 and 40, and further including any of the presently identified human types known in the art. Thus, in some embodiments, the methods involve transfecting the cell with a vector expressing one or more genes necessary for AAV replication, AAV gene transcription, and/or AAV packaging.

In some cases, a novel isolated capsid gene can be used to construct and package recombinant AAV vectors, using methods well known in the art, to determine functional characteristics associated with the novel capsid protein encoded by the gene. For example, novel isolated capsid genes can be used to construct and package recombinant AAV (rAAV) vectors comprising a reporter gene (e.g., B-Galactosidase, GFP, Luciferase, etc.). The rAAV vector can then be delivered to an animal (e.g., mouse) and the tissue targeting properties of the novel isolated capsid gene can be determined by examining the expression of the reporter gene in various tissues (e.g., heart, liver, kidneys) of the animal. Other methods for characterizing the novel isolated capsid genes are disclosed herein and still others are well known in the art.

The kit may have a variety of forms, such as a blister pouch, a shrink wrapped pouch, a vacuum sealable pouch, a sealable thermoformed tray, or a similar pouch or tray form, with the accessories loosely packed within the pouch, one or more tubes, containers, a box or a bag. The kit may be sterilized after the accessories are added, thereby allowing the individual accessories in the container to be otherwise unwrapped. The kits can be sterilized using any appropriate sterilization techniques, such as radiation sterilization, heat sterilization, or other sterilization methods known in the art. The kit may also include other components, depending on the specific application, for example, containers, cell media, salts, buffers, reagents, syringes, needles, a fabric, such as gauze, for applying or removing a disinfecting agent, disposable gloves, a support for the agents prior to administration etc.

The instructions included within the kit may involve methods for detecting a latent AAV in a cell. In addition, kits of the disclosure may include, instructions, a negative and/or positive control, containers, diluents and buffers for the sample, sample preparation tubes and a printed or electronic table of reference AAV sequence for sequence comparisons.

EXAMPLES Example 1

Development of Novel AAV Vectors for Muscular and Lung Gene Delivery: An Engineered Novel Capsid Variant of AAV9 for Muscle and Lung-Directed Transgene Expression

AAV-ClvD8 is an AAV9 variety with significantly reduced transcytosis property. Structural analysis of the ClvD8 capsid was performed using newly established AAV9 capsid structure as a template. This analysis revealed that other than the alteration at position 647, the other mutated amino acid (a.a.) residues in Clv-D8 (compared with AAV9) are located on the AAV9 capsid protrusions that surround the icosahedral 3-fold axis of AAV9 VP3 protein, which plays a role in receptor binding and cellular transduction.

In an attempt to map the a.a. residual(s) responsible for peripheral (primarily liver) tissue transduction by IV delivery of rAAV9, single and combinatory mutations for each of the a.a. on the AAV9 capsid that are mutated in AAV-ClvD8 were produced. Corresponding luciferase expressing vectors were delivered into C57BL/6 mice by intravascular (IV), intranasal (IN) and intramuscular (IM) injections to compare their luciferase transduction and vector genome biodistribution profiles with rAAV9 wild type (wt).

Using this approach, a novel capsid mutant of AAV9 was produced that is identified herein as AAV9.HR that generated significantly lower luciferase expression and vector genome abundance (VGA) in liver by all three routes and local tissue-restricted expression and genome persistence by IM and IN delivery. Other mutants that were produced using this method are identified herein as AAV9H, AAV9I, AAV9R, and AAV9Y (as depicted in FIG. 1).

FIG. 2A-C depicts that Clv-D8, which is a chimpanzee-derived AAV9-relative (Δ 4 a.a.), has abolished transcytosis capability. FIG. 2D shows that the blood clearance pattern is not change between AAV9 and CLv-D8, and other mutants of AAV9 (i.e., R533S, H527Y, and double R533S+H527Y compared with AAV9, referred to as AAV9R, AAV9H and AAV9HR, respectively) for IV or IM administration.

AAV9.HR (derived from CLv-D8, Δ 2 a.a.) displayed a blood clearance pattern similar to that of rAAV9 wt after IV, IM, and IN administration suggesting that its ability to cross vascular barrier from tissue to vessel was not impaired. Six-week old male C57BL/6 mice were injected via left tibialis anterior with AAV9 and its mutants (1.0 e11 GC/mouse, n=3). At specific time points (0-72 hrs), 5 μl of tail vein blood were collected, diluted 1000-fold into PBS and then proceeded for qPCR analysis. Standards were spiked with normal mouse blood (1000-fold dilution) without treatment. See FIG. 3.

Luciferase assays were performed to evaluate the distribution of AAVs in mice after IM injection. It was found that although AAV9.HR can enter vessel after IM injection, it is limited in its ability to enter major organ, such as liver, by transcytosis. See FIG. 4. The AAV9.HR mediated transgene expression is essentially limited in injected muscle.

In another experiment, six-week old male C57BL/6 mice were injected via tail vein (1.0 e11 GC/mouse) with AAV9 and its mutant vectors encoding luciferase gene. Four weeks later, specific organs were harvested for qPCR and luciferase activity analysis. The results are depicted in FIG. 5. It was found that AAV9.HR-mediated liver transgene expression is much lower than wtAAV9 after IV injection. (See also FIGS. 7 and 8.)

In another experiment, six-week old male C57BL/6 mice were injected via intranasal delivery (1.0 e11 GC/mouse) with AAV9 and its mutant vectors encoding luciferase gene. Four weeks later, specific organs were harvested for qPCR and luciferase activity analysis. The results are depicted in FIG. 6. It was found that AAV9.HR mediated transgene expression is limited in lung after IN delivery

Further assays were conducted in which four-week-old C57BL/6 mice were injected (IV, Retro-orbital injection, 1e12 GC/mouse,) with scAAV9 wt.CB6.PI.EGFP (n=3) or scAAV9HR.CB6.PI.EGFP (n=3); three weeks after administration, organs were collected and gDNA were extracted for qPCR analysis (Student's t-test (unpaired, two-tailed)). The results of these assay are depicted in FIG. 9 and illustrate differences in the biodistribution of AAV9 compared with its mutant vectors following IV administration.

A comparison was also made of AAV9 and AAV9HR-mediated neuron transduction after IV (RO) delivery into D1 C57B16 mice at 4×10¹¹ GC/mouse. Gene transfer was analyzed at 3 weeks post-injection. Comparable CNS gene transfer between these two vectors, as depicted in FIG. 10. The rAAV9.HR even leads to more neuron transduction (high ration of transduced neuron/astrocyte) in certain areas (hippocampus, cortex etc.) It was also found that rAAV9.HR leads to peripheral organs detargeting, as depicted in FIG. 11.

A comparison was also made of AAV9 and AAV9HR-mediated biodistribution after IV (RO) delivery into D1 C57B16 mice at 1×10¹² GC/mouse (a higher dose). Gene transfer was analyzed at 3 weeks post-injection. (FIG. 12.) Comparable vector genome abundance in CNS in adult animals between rAAV9 and rAAV9HR. AAV9.HR leads to ˜135-fold less vector genome abundance and significantly diminished transgene expression in liver (data not shown here) and other peripheral organs as compared to rAAV9

This work represents a significant advance in understanding vector biology of AAV9 and developing novel vectors with transduction efficiency similar to rAAV9 but improved safety profile for muscle and lung gene delivery and gene therapy of muscular, lung or other disorders.

Example 2

This example describes the use of AAV9.HR for CNS-directed gene therapy by intravenous (IV) injection.

A mouse model of Canavan disease was used in this study. Healthy control (WT) and Canavan disease (CD) mice were administered a dose of 4×10¹¹ genome copies (GC) of an rAAV vector containing the human aspartoacylase (AspA) gene (AAV9-FKzhAspA-OPT or AAV9.HR-FKzhAspA-OPT) at age p1 by intravenous injection. All untreated CD mice died by week 4. Enzymatic assays and western blot were performed on WT and treated CD mice at age p42. Administration of either construct prevented death of CD mice. FIG. 13A shows no significant difference in enzymatic activity of AspA in the brains of mice administered AAV9 or AAV9.HR. However, administration of the AAV9.HR construct did result in less off-target (e.g. liver tissue) expression of ASPA comparted to the AAV9 construct, as shown in FIG. 13B.

FIG. 14A shows similar localization patterns of hAspA expression in the brains of mice (age p42) after administration via AAV9 or AAV9.HR as measured by magnetic resonance imaging (MRI). Magnetic resonance spectroscopy (MRS) data demonstrates that hAspA expressed by both constructs is able to degrade N-acetyl-L-aspartic acid (NAA) (FIG. 14B).

FIG. 15 shows that mice administered the HR.FKzhAspA-Opt construct showed no significant difference in growth (as measured by weight) to either wild-type (WT) or AAV9.FKzhAspA-Opt treated mice. Untreated and vehicle-only treated CD mice died by 4 weeks of age.

Administration of HR.FKzhAspA-Opt to CD mice also improved motor and behavioral phenotypes (FIGS. 16-18).

The results described above demonstrate that a CNS-targeted transgene (hASPA) delivered by an intravenously injected AAV9.HR vector is functionally expressed and localized in a similar manner to AAV9-delivered hAspA. However, the AAV.HR vecotor provides the advantage of lower off-target expression that AAV9. The results further show that AAV9.HR-hAspA is effective in prolonging the life and improving motor phenotype in a mouse model of Canavan disease.

Example 3

This example describes the expression of secreted tumor suppressor proteins using AAV.HR vectors for cancer therapy.

Activated oncogenes can induce cellular senescence and/or apoptosis in vitro and in vivo. Oncogene-induced senescence and/or apoptosis may be a cellular mechanism to prevent proliferation of cells at risk for neoplastic transformation. One gene involved in this process is the BRAF oncogene, which is a serine-threonine protein kinase. BRAF is a downstream effector of RAS and signals through the MAP kinase pathway. Oncogenic BRAF-activating mutations (e.g. BRAFV600E) substantially increase protein kinase activity, resulting in constitutive ERK signaling. These activating BRAF mutations are found in 70% of melanomas, 15% of colorectal cancers, 30% of ovarian cancers and 40% of papillary thyroid carcinomas. Several factors are involved in BRAF-mediated senescence/apoptosis (Table 1).

TABLE 1 Factors involved in BRAF-mediated Senescence/Apoptosis BIN1 ILIR1 RAP1GAP TP53 SMARCB1 BNIP3L HSPA9B PEA15 NF2 BUB1 IGFBP7 DMTF1 FOXA1 MEN1 HIRA IRF1 FBXO31

Previous studies have shown IGFBP7 suppresses growth of BRAFV600E-positive tumors in mouse xenografts. Furthermore, IGFBP7 suppresses melanoma metastasis and enhances survival in mice with tumor xenografts. Another protein that has potential use as a cancer therapeutic is Sushi repeat-containing protein (SRPX), which has been shown to be down-regulated in many human lung cancers. SRPX is predicted to be a secreted protein.

FIG. 19A shows that AAV9.HR-IGFBP7 has tumor suppression activity comparable to IGFBP delivered by WT AAV9. FIG. 19B shows the dose-dependent effect of AAV.HR-IGFBP7 on tumor suppression. The tumor suppressing activity of SRPX was also demonstrated. FIG. 20A shows the concentration-dependent effect of AAV9.HR-SRPX delivery on tumor size in Balb/c Nu/Nu mice. FIG. 20B shows dose-dependent expression of SRPX delivered by AAV9.HR vector. Due to the reduced transcytosis properties exhibited by the AAV9.HR vector, transgene delivery is reversible, whereas delivery by WT AAV9 vector persists even after removal of the injected tissue (FIG. 21). FIG. 22 demonstrates that AAV9.HR vector genomes do not migrate away from the tissue into which they are delivered.

The toxicity of transgene delivery by AAV.HR vectors was assessed by measurement of alanine transaminase (ALT) and aspartate aminotransferase (AST) (FIG. 23-25). AAV9.HR exhibits a similar toxicity profile to WT AAV9 at several dosages. These results indicate that AAV.HR is a safe and efficient vector for muscle delivering of the secreted tumor suppressor proteins as cancer therapeutics.
